It’s all about the fact that people want to achieve two things at the same time. We want to think of ourselves as honest, wonderful people, and then we want to benefit from cheating. Our ability to rationalize our own actions can actually help us be more dishonest while thinking of ourselves as honest. So the idea that everybody else does it, or the idea that nobody is really going to suffer, or the idea that the entity you are stealing from is actually a bad entity, or the idea that you don’t see it—all of those things help people be dishonest.
